SLIDABLE BRACKET.

Specification of Letters Patent. Patented Mal'. 16, 1915.

Application filed July 17, 1914. Serial-No. 851,575.

, T0 all whom it may conc-ern.'

Be it known that I, PETER STAUBER, a

citizen of the United States, residing atl Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and l useful Improvements in Slidable Brackets,

of which the following is a specitication.

. This invention relates to improvements in supports and more particularly in slidable brackets.

The leading feature of my invention consists in providing a simple, inexpensive, and highly eflicient bracket which is adapted to slide upon a suitable sustaining member or support and which may be automatically locked to any desired adjusted position.

A further object of my invention is to provide a device of the above character so constructed and arranged as to permit saidl bracket to slide upon a suitable guide upon the application of force in one direction and to lock said bracket against movement upon said guide upon the application of force 1n a contrary direction.

With the above and further objects in view my invention consists in the combination, arrangement, and details of construction disclosed in the specication and drawings, and then more particularly pointed out in the appended claims.

In the drawing where similar reference characters designate similar vparts throughout the respective views,

Figure 1 is a side elevation partly broken away of my invention showing the parts in assembled relation, Fig. 2 is a top plan View of Fig. 1, Fig. 3 is a side elevation of the slidable bracket, Fig. 4 is a detailed view in plan Vof the guide, Fig. 5 is a front elevation of said guide, and Fig. 6 is a side elevation of the guide, Fig. 7 is a side elevation of the racket bar to be described. Fig. 8 is a detail perspective view of a modification of my invention to be described.

Referring to the drawings which are merely illustrative of my invention a suitably constructed guide is shown consisting of the longitudinal back plate 1, and of the coextensive channel-iron guide 2 which is formed with the oppositely disposed substantially right angular flanges 3 secured as by rivets upon said back plate, it being understood that said back plate will be secured upon any vertical or other support.

The guide 2l is provided with a longitudinal s lot 4 disposed substantially at a median line through which is adapted to .project the bracket arm 8 to be described. Secured upon one of the sides of the guide is an elongated ratchet bar 5 provided with a series of ratchetteeth 6 providing jagged recesses, said teeth projecting forwardly' of the front face ofsaid guide 2,`and being secured as by suitable rivets 7 upon said guide. i

A bracket arm is designated 8 Vwhich projects through the slot 4 and extends transversely of the guide 2, and the two 4channel irons 9 have'their bases secured -in contact upon the opposite sides of the projecting end of said arm 8 and a suitable pivot 10 connects said channel irons,9, the vlatter being suitably guided in the guides 2 and forming a slide for said arm 8, being of such dimensions as to be held against any displacement or movement in the guide. The diagonal strut 11 is secured at one end to the forward' end of the bracket arm 8 and a depending brace 12 connects the rear end ot said arm to said strut, said strut 11 being formed the brace 12 is deflected obliquely and laterally of the arm 8 as at 14 and is provided with terminal feet 15 secured respectively uponthe arm 8 and strut 11 such as by rivets 16 or other suitable means. able stop 17 is secured at any suitable point upon the channel irons 9 so as to be in substantial alinement with the slot 4 to enable the arm 8 to rest thereupon and to assume the horizontal position such as is shown in the drawings. I

In Fig. 8 a modification of my invention is shown. A different form of brace is disclosed formed and shaped from sheet metal, which will be bent so as to provide the parallel sides 13', the web 10 and the right angularly disposed outurned ears 14. It will be noticed that the ears 14 are formed obliquely with respect to the sides 13 and may bear against the web 3 of the guide, the web 10 being of such a width that it may rest upon any of the teeth'; the web 10 is cut away as at 16 whereby to enable the arm 8 to pass between the sides 13 and be secured thereto by any suitable means such as rivets 17. formed preferably integrally upon one of the side edges of the slot 4- of the guide. T he arm 8 in all substantial particulars has the pivotal mounting hereinbefore described.

ln operation when it is desired to move the bracket the pawl or tooth 13 will be moved out of engagement with the ratchet tooth concerned by applying force or pressure upon the arm 8 to move the same upon the pivot 10 by a lifting action whereupon the slide consisting of the channel irons 9 may be slid in the guide 2 to any adjusted position, and when it is desired to lock the bracket against movement the force or pressure will be applied upon the arm 8 in such a way that the tooth 13 will be brought to bear upon any of the ratchet teeth 6 whereupon the arm 8 will rest upon the stop 17 yso that the weight sustained by the bracket will all the more eiiectively hold the' teeth 13 in engagement with the ratchet tooth 6 and serve to hold the bracket arm 8 in horif Zontal position.

Numerous modifications may be resorted to in practice without departing in principle from the details of construction herein disclosed save as falling within the purview of the appended claims.

What I desire to claim and secure protection on is 1. 1n combination a guide, a bracket arm, a slide mounted in said guide, said guide having a slot through which said arm projects, a pivot carried by said slide upon which said arm is fulcrumed, and means carried by said arm adapted to engage with said guide to hold said bracket arm against movement.

2. In combination a guide, said guide having a longitudinal slot, a bracket arm projecting through said slot into said guide, a slide connected to the projecting end of said arm, a pivot carried by said slide upon which said arm is fulcrumed, a ratchet bar carried by said guide, a pawl carried by said arm engaging with said ratchet bar to lock said ratchet bar against movement,

The ratchet teeth 6 are said pawl being retractable from said ratchet bar.

8. In combination a guide, said guide having a longitudinal slot, a bracket arm projecting through said slot into said guide, oppositely disposed channel irons mounted in said guide, a pivot connecting said channel irons and said bracket arms, a stop moving in unison with said slide externally oi' said guide, said bracket arm adapted to rest upon said stop, and a strut connected at one end to said bracket arm, and a pawl carried by said strut at its free end, and a ratchet bar carried by said guide with which said pawl is adapted to make engagement.

et. A device of the kind described coinprising a guide, said guide having a longitudinal slot, a bracket arm projecting through said slot into said guide, a slide in said guide, a pivot carried by said slide upon which said arm is fulcrumed, a ratchet bar connected to one side of said guide, a strut connected obliquely at one end upon said arin and an integral tooth formed upon said strut adapted to engage with said ratchet bar.

5. A device of the kind described comprising a guide, oppositely disposed channel irons slidably mounted in said guide, a

bracket arm, said guide having a slot through which said bracket arm projects, a pivot connecting said channel irons and said arm, a-ratchet bar mounted laterally upon said guide, said ratchet bar having teeth projecting forwardly of said guide, a strut connected at one end to said arm, an integral tooth formed upon said strut arranged to engage with said ratchet bar, a stop moving in unison with said slide and adapted to steady said arm in horizontal position.

ln testimony whereof l affix my signature in presence of two witnesses.

PETER STAUBER.
